[Our current technique for basic pterional craniotomy].

Abstract

Pterional cnaniotomy is frequently used in neurosurgical practice, but still poses significant cosmetic and functional drawbacks. Here, we describe our modified technique to overcome such problems as the sterilization of the scalp without brush and razor, preemptive analgesia, preservation of the periostium for reconstruction, retrograde dissection of the temporal muscle, and complete sphenoidotomy using chisel or drills. The tips of our pterional craniotomy offer suitable size and depth of working field around the paraclinoidal regions, maintaining cosmetic satisfaction of the patients.

Non-invasive intraoperative monitoring of blood pressure and arterial pCO2 during surgical anesthesia in mice.

Despite the constantly increasing use of genetically engineered mice in biomedical research, control of crucial physiological parameters such as blood pressure and arterial blood gases is difficult to achieve in temporarily anesthetized mice due to lack of techniques for reversible arterial cannulation. Here we report that arterial blood pressure and blood gases can be measured reliably in anaesthetized and artificially ventilated mice using non-invasive technology. C57Bl6 mice were anaesthetized by i.p. injection of midazolam, fentanyl, and medetomidin, intubated, and ventilated for 3h. End tidal pCO2 was monitored by micro-capnometry. Arterial blood pressure was measured non-invasively using a tail cuff. Non-invasive blood pressure (NIBP) correlated strongly with the invasive arterial blood pressure measured at the external carotid artery (r = 0.99, P < 0.001) and end tidal pCO2 values correlated very well with arterial blood pCO2 (r = 0.93, P < 0.001). The current results demonstrate that it is possible to reliably measure and control the most relevant physiological parameters in anesthetized mice. Thereby the current study may help to reduce animal numbers and perform mice experiments under more defined and controlled physiological conditions in the future.

Comparison of recoveries from anesthesia of horses placed on a rapidly inflating-deflating air pillow or the floor of a padded stall.

OBJECTIVE: To compare recoveries from anesthesia of horses placed on a conventional padded stall floor or on a specially designed air pillow. DESIGN: Prospective study. ANIMALS: 409 horses (> 1 year old) that were anesthetized for surgical procedures during a 37-month period. PROCEDURES: By random allocation, horses were allowed to recover from anesthesia in either a foammat-padded recovery stall or an identical recovery stall equipped with a rapidly inflating-deflating air pillow. All recoveries were videotaped for subsequent analysis by an independent evaluator. Times to first movement, first attempt to attain sternal recumbency, attainment of sternal recumbency, first attempt to stand, and successful standing were recorded. The numbers of attempts before achieving sternal recumbency and standing were counted, and scores for quality of standing and overall recovery were assigned. Recovery-related variables were compared between groups. RESULTS: Compared with horses allowed to recover in a conventional manner, horses that recovered from anesthesia on the air pillow had a significantly longer rest period before attempting to attain sternal recumbency and rise to standing. Once the pillow was deflated, horses were able to stand after significantly fewer attempts and the quality of their standing was significantly better. Between the 2 groups of horses, there was no significant difference in overall recovery quality scores. The air pillow and padded floor systems were equally safe. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that use of a rapidly inflating-deflating air pillow promotes a longer period of recumbency and a better quality of standing after anesthesia in horses.

Representation of the spatial relationship among object parts by neurons in macaque inferotemporal cortex.

We investigated object representation in area TE, the anterior part of monkey inferotemporal (IT) cortex, with a combination of optical and extracellular recordings in anesthetized monkeys. We found neurons that respond to visual stimuli composed of naturally distinguishable parts. These neurons were sensitive to a particular spatial arrangement of parts but less sensitive to differences in local features within individual parts. Thus these neurons were activated when arbitrary local features were arranged in a particular spatial configuration, suggesting that they may be responsible for representing the spatial configuration of object images. Previously it has been reported that many neurons in area TE respond to visual features less complex than natural objects, but it has remained unclear whether these features are related to local features of object images or to more global features. These results indicate that TE neurons represent not only local features but also global features such as the spatial relationship among object parts.
